6 claims. (01. 197- 84) two processes employed in the This invention relates to a justifying and variable spacing and typing machine.

It is an object of the invention to provide a machine of the character described especially adapted for use in that branch of the printing art commonly referred to as lithography or off-- set printing.

Another object 'of the invention is to provide an improvement in a conventional typewriter, or similar typing machine, wherein regularly formed standard type letters, such as are used in printing, may be substituted forthe conventional typewriter typewith means for spacing the letters or characters in accordance withtheir width.

In the ordinary typewritenor typing machine, 'the lower case letters are of the same width, that is, each occupies the same amount of space in the line as any other, consequently the platen carriage and platen move a uniform distance, or space, for each letter; the above is also true for upper case, or capital letters, or characters.

It is another object of the present invention I to provide a' typing machine having standard 25 type, such as is used in printing and wherein the type varies in width, being narrower, and

some letters, or characters, occupying lessline space,

than others and wherein the platen carriage and platen moves a distance corresponding to the 30 line space required in accordance with the width justify the completed of letter press or character, last imprinted on the work. Inother words, the invention embodies means for variably spacing the letters, or characters, imprinted on the work in accordance with the'line space required by such letters, or characters. 1

Another object of the invention is to provide, in combination with a printing machine, a camera for photographing each completion with means for adjusting the camera toward and from the work of the letter,

and then photographing them on a continuous roll of sensitized fllm which is automatically moved, one line, depth measure, at a time 'and the film rewound from the original, or storage reel, on to a receiving reel. Oifset printing, or lithography, is produced, at

the present time, from photographic printed plates and the plates themselves are made by transferring the image on the film, or negative,

hence a negative of the subject requisite. By theuseot loyed it is necessary to to a zinc plate,

printing, to take a press proof and then produce therefroma negative on asensitized By the use of ing typing machine hereinafter the justuymg'eud variable ,spacthereof. I

ings wherein printed line upon its to automatically lines'to the same length 'bar I and clutch bar 6. associated with the brake bar and consists of described. th r methods heretofore used, to-wit, the setting up of letter press type and the proofing of such type are eliminated.

With the above and'other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

This typingmachine has the transversely movable carrlage 2 of the usual construction which carries the cylindrical platen 3. The carriage has the'depending bracket arms 4, 4 at the rear er the machine to the lower end of which there is fastened the" rear and front'transverse brake An electrical brake is electro-ma'gnet. or solenoid I having the core 8 in contact with the brake bar- I. The electro-mag- I. II and the electric circuit may be, completed or broken by a conventional switch I l with which one of the 'conductors is equipped. when the electro-magnet is energized the brake bar 5, as well as the clutch'bar i will be held against movement. When secured to andextended transverselyacross the switch is opened the electric brake willbe released.

the rear end of the framework I there is a guide plate l2'having the guides l3 therethrough to the compression spring 29.

snugly receive the spacing dogs. l4. On the upper and lower margins of the guide plate l2 are the transverse cleats I5, I 6, having a dove-tailed connection with, and forming tracks for, the spacing bar IT, as more clearly shown in Figure 1. This spacing bar is movable transversely, its range of movement being limited in one direction by the end stop I.

Upstanding from the spacing bar I! there is a bracket l9 and pivotally connected to the upper end of said bracket there is a depending clutch lever 20. The lower end of this clutch lever has the spaced upper and lower clutch jaws 2|, 22 which are spaced apart a sumcient distance to receive the clutch bar 6 snugly between them. The bracket I9 is countersunk into the rear side of spacing bar i I, and'extends beneath it, as shown in Figure 7 and the pull spring 23 Eattached, at one end, to the lower end of the lever 20 and at its other end to the bracket l9 and normally this spring holds the clutch lever 20 in angular relation to the bar 5 so as to cause said jaws 2|, 22 to grip' the upper and lower margins of the bar 6 so as to hold said bar against movement. f

.The upper end of the lever 20 has an overturned release arm 24, presenting a flat upper bearing face 25. Upon downward movement of the arm 24 the clutch lever 20 will be moved so as to cause the gripping surface of the jaws 2|, 22 to move into parallel relation with the margins of the bar 6 whereby said bar will be released from the gripping action of the jaws 2|, 22 and permitted to move. Upon'release of the jaws the pull spring 26, attached at one end to the bracket 19, and at its other end to the frame I will cause a movement of the space bar H, the range of said movement being limited by one of the dogs l4 as hereinafter explained.

The space bar IT has a series of openings, as 21 therethrough, into which the spacing dogs l4 may be projected, as hereinafter explained, and as shown in Figure 7 and Figure 9. It may be here noted that there is a spacing dog, and a corresponding spacing opening, in the bar I! for each type key lever and one for the spacing lever.

The numeral 28 designates a conventional key lever which is pivoted, at its inner end to the frame and which is normally held elevated by Corresponding to each key lever there is the conventional type bar 30 pivoted to the main frame and whose forward, or free, end is provided with lower and upper case type 3|, 32. r The other end of the type bar has the diagonal slot 33forming a bearing for the pin 34 which extends out laterally into said slot from the upper end of the type bar link 35 which is pivoted at its lower end to the main frame and has the forwardly extended arm 36 which is provided with an oblong slot 31 to receive the stud 38 which extends out laterally from the corresponding key' lever 28. Upon depression of the key lever the upper end of the type bar link 35 will be thrown forwardly and the free end of the type bar 30 will be actuated upwardly to carry the type into printing relation with the platen 3 in the conventional manner.

' The inner end of each spacing dog I4 is pivotally connected to the upper end of an actuating. lever 4| and the lower end of this lever is connected to the type bar link 35 by means of the tie 42 which includes a compression spring 43. Accordingly upon actuation of the type bar link 35, the corresponding dog l4 will be projected through its aligned opening 21. Upon release of the key lever'28 the spring 29 will elevate it to its original position thus releasing the tension on the compression spring 43. Thereupon the pull spring 44 will operate through the lever 4| to retract the corresponding dog [4. This pull spring 44 is attached, at one end, to the main frame I and at its other end to the free end of the lever 4|.

The dogs l4 operate through the vertically elongated openings, or guides, in the guide plate l2, as hereinabove explained, whereby the dogs I 4 may be shifted vertically in said guides, for a purpose to be hereinafter explained, as the shift lever 55 is manipulated to shift from lower case. to upper case letters. This shifting is ac complished in the conventional manner. The inner end of the shift lever is pivoted on the mainframe in the same manner as the key lever 28. The pivoted end of the shift lever 45 has an upstanding finger 46 whose upper end is forwardly curved and rides against the bearing face 47- of the depending arm of the bell crank 48. There are two of these bell cranks, one at each side of the machine and the free ends of their horizontally extended arms support a transverse -rod 49 which forms a track on which the roller 50, runs in the conventional manner. The conventional platen support is designated generally by the numeral 5| and the roller .50 is carried by this platen support. Upon actuation of the shift lever 45, the finger 46 will be actuated forwardly and the track 49, the platen support, and the platen will be elevated. When the platen is in lower position the lower case letters 3| cooperate therewith and when elevated the upper case letters 32 cooperate therewith in the well known manner.

The dogs M are mounted in a magazine 52. This magazine has the forwardly directed bracketa 53 on which the respective levers 4| are pivoted and the ends of the magazine 52 are supported on the lift levers 54, one at each side of the machine. The forward ends of the lift levers are pivoted to the framework and these levers are connected to the horizontal arms, of the bell cranks 48 by the lift lever rods 55. Accordingly, upon the actuation of the shift lever 45 the lifting levers 54 and magazine 52, with the series of dogs-I4 therein; will be elevated to upper position. The dogs i4 work through bearings 52a of the magazine.

Upon actuation of a key lever 28 the corresponding type bar 30 will be operated as explained and upon operation of any type bar it will strike the transverse thrust bar 56'. This thrust,

bar is supported by an upstanding guide 5'! whose upper end is forwardly turned and extended through a bearing in the framework of the machine.- Extending rearwardly from the thrust bar 56 is a thrust rod 58 whose rear end is pivoted to the free end of the'upstanding arm of the bell crank 59. 'The other arm of said bell crank has a pivotal connection with a vertically movable switch-actuating rod 60. The lower end of this red is aligned above the push rod 6| of the switch ll. When a type bar is actuated as above stated there will be a rearward thrust imparted to the rod 58 and a downward thrust to the rod closing the'switch Upon release of the key lever the bell crank 59 will be moved to original position by the pull spring 62, one end of which is attached to the upstanding arm of said bell crank? and the other end of which is attached to a stationary part of the framework. Upon closing of the switch H the electric brake hereinabove referred to will be rendered active to hold the brake and clutch bars 5, 6 and the carriage of the machine stationary.

There is a clutch release lever 63, one end of which is pivoted to a transverse yoke 65 which is supported on the upstanding standards 64, 64. The rear end of this release arm is downwardly turned and mounted thereon is a roller 66 which rides against the bearing face 26 of the laterally. extended arm 24. The upper end of the rod,6ll is connected to the' release arm 63 and upon downward actuation of the rod 60, as hereinabove' explained, the roller 66 will actuate the clutch lever 20 to release the clutch shoes 2|, 22- thus permitting the spacing bar I! to move, under the influence of the spring 26, to the left as indicated in Figures 7 and 9 and upon release of the key lever and the subsequent upward movement of the rod 60, under the influence of the spring 62, the roller 64 will be released from the face 25 and the spring 22 will thereupon operate to again apply the mechanical clutch to the'bar 6.

The humeral 61 designates a space bar lever.

In the conventional type of typing machine there are two of these levers, one on each side and connected, at their forward ends, by the space bar 68. At an intermediate point each space bar lever is pivoted on the transverse rod and upstand ing from one of said levers 61, at its pivotal mounting there is the arm 10. The free end of this arm is connected to the free end of the corresponding actuating lever by means of a tie.

'ii which includes a compression spring 13 so that upon actuation of the space bar 62 the dog ll corresponding to said bar will be projecting through its aligned opening 21. The forward ends of the space bar levers 61 are normally held elevated by the coil spring 14 which is connected at one end to one of said levers and at its other end to the framework above, The inner end of one of the space bar levers 61 carries an upstanding finger I aligned underneath the free end of the forwardly projecting arm I6 of the bell crank 66. When the space bar 68 is depressed the finger 69 will elevate the arm 16 moving the rod down-' wardly, closing the switch H, as before and setting the electric brake to hold the brake bar 5 and clutch bar 6 against movement and releasing the mechanical clutch to permit retraction of the spacing bar l1, under the influence K of the spring 26 as hereinabove explained thus controlling the spacing between the typed words or characters. Upon release of the space bar 66 it will be elevated by the spring ll thus releasing the corresponding dog actuating lever I] and per mitting the corresponding spacing dog ll to be re-.- tracted by the corresponding pull spring ll.

The carriage 2 ls moved by the conventional means for that purpose. As shown in Figure .2 there is an involute spring housed within the housing 'l'l with its free end 16 attached to'the carriage. I

As also clearly illustrated in Figure 2, the openings 21 vary in width and likewise the corresponding dogs I, which work through said openings also vary in width; The upper ends of said openings as 21a are widened laterally as also shown in Figure 2 and for a purpose to be hereinafter stated. w

The faces of various letters and characters used in printing, and of the regular printing type, vary in width over a wide range from the narrowest of lower case letters to the widest of upper case letters. However, in the ordinary typing machine the spacing for the letters-and characters used is the same. Inrorder to adapt a typing machine, however, for use in lithography or offset printing, it is necessary to provide for variable spacing, rather than the uniform spacing so that spacing for each letter, or character, .will vary in accordance with the width thereof; and this should be done automatically. By the use of the present invention this automatic variable spacing may be accomplishedthat is, the carriage is automatically released andpermitted to move only the required space for .each individual letter,-or character, as his printed on.the work. The

movement of the carriage, that is, the spacing,

' will be actuated to cause a lower case letter ll to come into contact with the workand print the.-

letter or character thereon.- At the same time the switch I lfwill be closed and the electric brake rendered operative to hold the brake bar 6, he clutch bar 6 and the carriage against moveme t. The clutch lever 20 will also be operated to release the clutch jaws 2|, 22 from the clutch bar 6 thus releasing the spacing bar I! to the pull of the spring 26. The depending on the relative width of the opening and the dog which has been projected through said opening. The relative width of said dog and opening should correspond tothe width of the letterjor character, just impressed or printed on the work. The distance of this movement is indicated by the letter E (see Figure 9). Upon release of the key lever the switch II will be-opened releasing the electric brake and the roller 66 will be released from the arm 24 to permit the spring 23 to engage the clutch shoes 2|, 22 with the clutch bar-6. The carriage, clutch bar 6 and spacing ,bar I! are now clutched together and can move only the distance indicated by E, Figure 9, whereupon the spacing bar l1 will engage the stop l6. It will be seen that the carriage has moved only the distance required for the width of the letter or character, just imprinted on the work. Each dog II and its corresponding opening II are of such relative width as to allow the carriage to move only a distance corresponding to the width of the letter or character, last imprinted on the work.

when upper case or capital letters areto be used the shift lever may be depressed thus elevating the carriage, as hereinabove explained and at the same time correspondingly elevating the magazine 62 so as to carry the dogs l4 into alignallow a greater range of movement of the spacing bar II. The widened portions 21a vary in width bar I! will then move a distance e5 ment with the widened portions 210 of the openin accordance with the variations in width of the corresponding upper case letters. Otherwise the operation of the machine is the same as it is in the case of the lower case letters as before explained.

Variations in the widths, and the corresponding spacing, of the printed letters, or characters, are illustrated in the diagram shown in Figure 5.

Referring to Figures 10, 11, 12 and 13 means are there disclosed for justifying the printed lines from an approximate length, or measure to an accurate length, which justifying means will now be described:

The numeral I9 designates a conventional type of camera wherein there is mounted, for movement, a sensitized film 88. The film is moved by any conventional mechanism suitable for the purpose and is exposed by a conventional shutter mechanism of any selected type. Fastened to the carriage 2 of the typing machine and movable therewith, and arranged at a suitable inclination with respect thereto there are the tracks 8|, 8!. 4 Slidably mounted on these tracks are the camera supporting bars 82, 82 which support the camera as shown. The camera is held in normal position by the actuating bar 83 and the actuating lever 88. This bar and lever are pivotally connected together at their outer ends as shown in Figure 12 and the lever is pivoted at its other end on one of the tracks BI and is provided with a guide finger 85 which normally rides against the forward straight edge 86 of the justifying bar 81. The bar 8? is fastened to the framework 8 with its forward straight edgev 86 aligned with the tracks along which the carriage 2 moves. The pivotally mounted end of the lever 89 has a rearwardly directed arm 88 on which a bearing pin 89 is mounted, Pivotally mounted on the other track 8| there is a shift lever '98 and one end of the cross-link 9! is pivotally connected to one end of this lever 90. The other end of the cross-link has an oblong bearing 92 in which the pin 89 works. The other end of the lever 98 is extended and formed with a grip 93. The outer end of the actuating bar 83 is reduced and works a through a bearing through the bearing member 79a on the bottom of the camera and is provided with an enlarged head 83a which is engageable with the bearing'member 19a. The actuating bar has a stop 83b and surrounding the reduced end of said bar and interposed between said stop and the bearing member 19a is a coiled spring 830.

There is a brake rod 94 mounted in suitable bearings 98, 91 and arranged parallel with one of the tracks 8|. A section 94a of this brake rod is formed square andslidably mounted thereon is a sleeve 98. Upstanding from this sleeve 98 there is an arm 99 and connected at one end to the upper end of this arm and at its other end to the conventional shutter operating mechanism of the camera there is the operating link I 88.

On the sleeve 98 there is a brake shoe IN. on the inner end of the brake rod 94 there is an upwardly inclined arm I82 arranged underneath the shift lever 98.

,When the end of a line has been reached and it is desired to return the carriage to position to begin another line the lever 98 may-be actu- ,ated in a direction indicated by thearrow in Figure 12. This will operate, throughthe conventional rack-and-dog arrangement I83, to impart a partial rotation to the platen of the typing machine in the usual way to bring the completed line of printing in alignment with the ,camera and the lever 98 will thereafter contact with the arm I82 and depress the same partly turning the brake rod 94 and carrying the shoe I8I into frictional engagement with the adjacent track 8i and at the same time acting through the link I88 to operate the shutter of thebe exposed and a photograph of the printed line l'ast completed will be imaged on the film. Continued pressure on the lever 98 will return the platen carriage and platen, with the work thereon, to starting position.

Upon release of the lever 98 the finger 85 will contact against and move along the forward straight edge 86 of the justifying bar 81 as the next succeeding line is typed.

Each printed line will begin at a definite uniform margin indicated by the letter F of Figure 12, which point is common with the corresponding, or left line G, defining the field of the visual angle of the camera. This margin of the field is constant and the tracks 8i, 8! are arranged at such angles to the line of travel of the carriage as to maintain the left margin of the field constant with relation to the work as the camera moves forwardly or backwardly as hereinafter stated. The right margin of the field, when the camera is in its normal position, is indicated by the line H, Figure 12 and is common with the margin at which the printed lines end at I. Upon printing, should the line terminate within the field determined by the lines G and J it will not be justified but will be photographedfrom the normal camera position, but any line terminating between the points determined by the lines J and K will be justified to give a photographed line of normal length, that is, a length equal to, or approximately equal to, the length of a line which extends between the two margin"- points F and I. When the printed line extends past the point determined by the line J the finger 85 drops into the notch I84 at the end of the straight edge 86 and thereupon the pull spring 95- will move the camera forwardly, or bring it closer to the work, thus lengthening the short line, imaged on the film, to regulation length. As the length of the printed line increases to the point I the finger 85 will ride along the forwardly inclined guide I85 thus moving the camera backwardly or away from the work,- with the result that the amount of justification decreases until the camera reaches its normal position. Thereafter, as the length of the printed line increases past point I the camera moves farther away from the work thus shortening the line, imaged on the film, to, or approximately to, the desired length of line. At the termination of the movement of the lever 98 to actuate the shutters of the camera, the outer end of the slot 92 will engage the pin 89 thus actuating the lever 84' and releasing the finger 85 so that it will not engage in the notch I84 upon return movement of the platen carriage and platen to starting position. During this final movement of the lever 98, to actuate the lever 84. the camera 91 being held against movement by the brake I8I the spring 830 will be placed under compression thus allowing a certain independent movement of the. bar 83 relative to the camera. However, with the lever 98 in its rorera 19 will move in harmony with the movement of the lever 84 as the finger 85 moves along the inclined track M5, the spring 830 sufficient strength for that purpose.

When the carriage is returned to starting position, as hereinabove explained, the coil spring 95, connected at one end to the front supporting bar 82 and at its other end to one of the tracks II, will return the camera to original or normal position.
